I agree with all of the points. Number 10 is always a sticking point. For me, if i don't know the buyer, I will always leave feedback after the transaction is complete. The transaction for me is complete when the buyer has received the chip and is satisfied. I offer a money back and shipping back guarantee. Once the buyer is happy with the chip, I'm more then happy to leave positive feedback.

Again, thanbks for putting all of the points down. Great post!
